Yeah, this is bad and it indicates that there is a bug in the kernel
where some syscall did int x = splfoo(); and did not call splx(x);
before it returned. I think that the stack trace might show you
the offending syscall(). in ddb type 't'.
oh, and spl stands for set processor level, meaning set the level
of interrupts you want to process, masking the rest.
